Abstract
The internal and/or external magnetic fields of a coil are nullified to ad structurally detrimental Lorentz Forces and/or environmentally hazardous magnetic fields, in accordance with preestablished design objectives.
Claims
exact text as granted — not AI-modifiedWhat we claim is:
1. In a coil having turns in separate windings which are disposed about a common axis, the improvement comprising: the turns of the windings are angularly oriented relative to the axis with an equivalent angle existing between each turn and the axis to result in equal internal and equal external magnetic field components being induced along the axis and perpendicularly to the axis respectively, by the turns when equal current is passed through the windings with the direction of current in the windings determined to derive cumulative and/or nullifying internal and external magnetic field components in accordance with the intended use of the coil.
2. The coil of claim 1 wherein the axis is linear.
3. The coil of claim 1 wherein the axis is arcuate.
4. The coil of claims 1 wherein the turns of the windings are arranged in parallel, with each turn of one winding adjacent to a turn of the other winding and nullifying internal and external magnetic field components are induced by passing equal current through the separate windings in opposite directions about the axis.
5. The coil of claim 4 wherein the axis is linear.
6. The coil of claim 4 wherein the axis is arcuate.
7. The coil of claim 1 wherein the turns of each winding are disposed to cross the turns of the other winding and cumulative external magnetic field components, along with nullifying internal magnetic field components are induced by passing equal current through the separate windings in opposite directions about the axis.
8. The coil of claim 7 wherein the axis is linear.
9. The coil of claim 7 wherein the axis is arcuate.
10. The coil of claim 1 wherein the turns of each winding are disposed to cross the turns of the other winding and cumulative internal magnetic field components, along with nullifying external magnetic field components are induced by passing equal current through the separate windings in the same direction about the axis.
11. The coil of claim 10 wherein the axis is linear.
12. The coil of claim 10 wherein the axis is arcuate.Join the waitlist — get patent alerts
